States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Consider the following four liquids:
HF NaF ClF F2
a. Predict the relative boiling points by ranking them from lowest to highest. Explain your answers
b. At certain pressures, ClF forms a solid that sublimes when heated. Using a few words and a simple diagram, explain what is happening when ClF sublimes upon heating. Answer and describe the differences in the two
